State Grid Corp. of China has started up the world’s longest and most-powerful ultra-high voltage power line from its far northwest to the heavily populated east.
The 1,100-kilovolt direct-current Changji-to-Guquan project stretches 3,293 kilometers (2,046 miles), the nation’s biggest electricity distributor said in a statement Wednesday. That’s roughly the distance between Los Angeles and Cleveland. The 40.7 billion yuan ($5.9 billion) project, which the company referred to as the “Power Silk Road,” was approved in December 2015 and construction started the next month.
